Olive Oil (Extra Virgin)
Central fat of the Mediterranean and Blue Zones diets. Rich in oleic acid and polyphenols like oleocanthal — with robust cardiovascular evidence (PREDIMED).

Dr. Gundry
Gundry endorses extra-virgin olive oil without reservation as the primary fat source. He treats it as the key carrier for polyphenols (chiefly oleocanthal, hydroxytyrosol) that dampen inflammation and support endothelial function. He is strict about quality — cold-pressed, dark bottle, recent harvest.
Dr. William Li · 5×5 system
Li ranks EVOO among top foods across multiple defence systems. Oleocanthal is anti-angiogenic in vitro against tumour vasculature (relevant to angiogenesis balance), polyphenols protect DNA from oxidative stress, and the monounsaturates support membrane regeneration.
Biolazar evidence
The evidence is unusually strong for a food — PREDIMED remains one of the only nutrition RCTs to show a cardiovascular endpoint reduction from a specific food. Important: the effect is tied to EVOO, not refined olive oil (which lacks the polyphenols).
How to use
1–2 tbsp daily, cold over salad, vegetables, or soup. Do not overheat — polyphenols degrade at high temperatures. Look for a fresh, slightly peppery throat sensation (oleocanthal signal).
